@raven-worx . Yes, I also ran Qmake after cleaning.

So, how about posting a stacktrace?
Guessing only get's us so far.

[milan]

@J.Hilk . Sorry for my late reply. This is stack trace.

@milan
try updating your Intel graphics driver to the latest version

Also what graphics chip do you have exactly?
Did you specify any OpenGL related properties for your application?

[milan]

@raven-worx . Also, I get this.

HEAP[myApp.exe]:
Invalid allocation size - 2d7665640000000a (exceeded 7ffffffdefff). And following exception:

[milan]

@raven-worx . I have Intel HD Graphics 630 and Nvidia Quadro M620. No, I am not using any OpenGL. I do have a QtQuick Widget.

[milan]

@raven-worx. Thanks, you are right. It is Intel graphics driver issue.

[raven-worx]

@milan
did you solve it with an driver update?

[milan]

@raven-worx . Yes, it is already resolved. But, I do not understand which widget is using OpenGL.

QQuickWidget (=> QML)
Unless you explicitly tell it to use the software rasterizing backend.
e.g. either via code QQuickWindow::setSceneGraphBackend(QSGRendererInterface::Software); or via environment variable QT_QUICK_BACKEND=software
(before QApplication instantiation)
